Application filed October 11, 1906. Serial No. 338.405.

Patented Jan. '1, 1907.

T at whom/it may concern:

Be it known that we, LEoPoLD LINKIE- wroz and-WILLIAM KLEIN, citizens of the United States, residing at Brooklyn, in the countyof Kings and State of New York, have invented certain new and useful 1mprovements in Butter-Pat Machines, of which the following is a specification, reference being had therein to the accompanying drawings.

Our invention relates especially to means and mechanism employed for forming butter into pats, particularly for use in restaurants, hotels, and the like, and has for its object the provision of a machine which shall rapidly and uniformly produce pats of the desired shape and size.

To attain the desired end, our inven'tion consists in certain novel and useful combinations 'orarrangements of parts, and peculiarities of construction and operation, all of which will be hereinafter first fully described, and then pointed out in the claims.

In the drawings, Figure 1 isa side elevation of a machine embodying our invention, and Fig. 2 is a like view of the opposite side thereof. Fig. 3 is a top plan view of the machine, and Fig. 4 is a bottom plan view thereof looking upward from below. Fig. 5 is a vertical cross-sectional view'at line a a of Fig. 3. Similar numerals of reference wherever they occur indicate corresponding parts in all the figures.

1 is the body or main frame of the machine, made of any suitable material and provided with clamps 2 for securing the ma-,

chine to a table or bench.

3 is a packing-cylinder extending from the bottom. of the body 1, constituting a compressing-chamber.

4 is a forming-die, of any desired configuration, removably held at the bottom of the cylinder 3 by a split ring 5, having a setscrew 6.

Mounted in bearings in the body 1 are two shafts 7 and 8, each carrying a drum 9, having radial slots 1 1, wherein are loosely mount-. ed movable blades 10, springs 12 normally holding said blades in an extended position, such outward movement being limited by retaining-rings 14, located in slots 13 at each end of the blades 10, as particularly illustrated in Fig. 5 of the drawings.

15 is a triangular bar or rod passing across the interior of the body 1, and 16 represents segmental bearings beneath thebar 15 ateach side of the interior of the body 1, the said bar 15 and bearings 16 serving to force the blades 10 into the slots 11 as the drums revolve to- .ward each other.

17 represents scrapers forced upward against the periphery of the drum, and the blades by springs 18.

19 is'a hot-water receptacle, having a lip 20, extending beneath the forming-die 4 and the cutting mechanism to be hereinafter described.

21 is adriving-shaft provided with a handle 23 upon a wheel 22.

24 is a an eccentric fixed on the shaft 21.

25 is a strap encircling the eccentric and connected to an arm 26, which, by means ofa bolt 27, provided with a thumb-nut 28, may be adjustably held in a slotted arm 29, loosely mounted on the shaft 8.

is a ratchet-wheel fixed on the shaft 8,

and 31 is a spring-controlled dog on the-arm 29, arranged to engage the ratchet-wheel 30.

32 is a driving-gear on the shaft 8, where- 'with meshes a corresponding gear 33 on the shaft 7.

34 is a dog for preventing the turning backward of the gear 32 and connected parts.

34 is an arm pivoted at 35 to the main frame or body 1. This arm is slotted at 36 a projecting stud 37 on the arm 26 engaging in such slot. At the bottom of the arm 34 is a foot 38, having a slot 39, carrying a block40, wherein is pivoted a spring-controlled dog 41, arranged to rotate a ratchet-wheel 42, carried by a vertical shaft 43, journaled at 44 and carrying a cutting -wheel 45, having blades 46.

When constructed and arranged in accordance with the foregoing descri tion, the operation of our machine is as fo lows: Butter being supplied to the spaces between the projecting blades of the drum at the left of the machine, as shown in Figs. 3 and 5 of the drawings, the driving-shaft 21 is caused to rotate, imparting reciprocation to the arm 26, and if the bolt 27 is set in the position shown in the drawings each revolution of the driving-shaft will carry a pair of oppositelydisposed blades 10 to the position of the pair shown in Fig. 5 as in contact with the bar 15. The next rotation of the drivin -'shaft carries the butter below the bar 15, whlch effectually prevents the return of such butter, compressing it within the cylinder 3. As the blades 'the configuration of the passage through the After each act of compression and eX- die. pulsion of the butter and while the drums are at rest the cutting-wheel revolves a portion of a revolution, a blade passing over the face of the die, severing a pat of butter from the mass within the compression-chamber and carrying it against the heated lip 20, such heat causing the separation of the pat from the knifeblade, the completed pat dro ping into any suitable receptacle.

aving now fully described our invention, what we claim as new therein, and desire to secure by Letters Patent, is

1. A butter-pat machine in which is com-- prised a pair of cylinders provided with blades adapted to force butter into a comression-chamber; means for retracting said blades within the cylinders or drums; means for cleaning the peripheries of the drums; a com ression-chamber; means for severing a pre etermined amount of butter from the bottom of the mass within the compressionchamber, and means for preventing adhesion of the severed pat to the severing mechanism.

2. In a machine of the character herein specified, a pair of feeding-drums provided with projecting retractile blades means for causing said blades to retract to the level of the fixed portions of the drums as they pass into a compression-chamber; means for cleaning the peripheries of the drums, and a compression-chamber.

3. In a machine of the character herein specified, a rotatable, slotted feeding-drum provided with a series of blades mounted in said slots, springs for forcing the projecting blades outward, and means for retracting the blades within the drum to the level of the periphery thereof in combination with a compression-chamber below the level of the axis of the drum, substantially as shown and described.

4. In a machine of the character herein specified, the combination with a compress1on-chamber and means for compressing butter therein, of an intermittently-movable cutting device, andmeans for applying heat whereby the severed pats of butter are caused to part from the severing mechanism.

5. In a machine of the character herein specified, the combination with the compressing-drums, and compression-chamber, of a triangular bar located above the compression-chamber having its apex uppermost with which the blades are arranged to contact, substantially as shown and described.

6. In a machine of the character herein specified, a compression-drum having a slotted longitudinal body, in combination with a series of blades mounted over sprin 'swithin said slots, said blades being slotte at each end, and a ring at the end of the drum located within said slots last mentioned, substantially as and for the uses and purpose shown and described.

In testimony whereof we hereto affix our signatures in presence of two witnesses.
